LAC7 — Phaseolus vulgaris

Summary

PHAVU_008G112200, symbol LAC7, encodes a laccase, a copper-containing oxidase with p-diphenol:oxygen oxidoreductase activity, copper binding, and redox activity. The product belongs to the multicopper oxidase family and is localised to the apoplast and extracellular space. In French bean, this gene is associated with lignin breakdown and anabolism, response to copper, and the transition from vegetative to reproductive phase. It is linked to flowering time, pollen development, and root hair development. Related genes in other species are associated with lignin content, flowering time traits, and drought tolerance, as well as phenotypes including arrhythmic circadian clock, early flowering, and early senescence.
